Microsoft is looking at the Barnes & Noble Nook – and they are willing to pay $1 billion for them.

Barnes and Noble stock rose 16% as news flew about Microsoft wanting to purchase the Nook e-reader, tablet and e-book business. This, just days after an announcement that Nook was allowing users to download via Google Play. Barnes and Noble also considered spinning off the Nook to its own company.

According to a document obtained by TechCrunch, if Microsoft was to obtain Nook, the Android-based tablet would be discontinued and the e-reader would be phased out at a later time. The expectation would be to merge Nook e-reader into the Microsoft Windows 8 tablet.

Right now, 10 million Nook devices have been sold, with 7 million active subscribers.
